[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figure 1 and Figure 2A multi-signal transmission harness cutting mechanism includes a base 100, a wire feeding assembly 200, a wire clamping assembly 300, and a cutting assembly 400. The wire feeding assembly 200, the wire clamping assembly 300, and the cutting assembly 400 are respectively mounted on the base 100, and the cutting assembly 400 is located between the wire feeding assembly 200 and the wire clamping assembly 300. The wire feeding assembly 200 is used to feed the wire and allow the wire to pass through the cutting assembly 400. The wire clamping assembly 300 is used to clamp the starting end of the wire and rotate it 180° after clamping to bend the starting end of the wire. The cutting assembly 400 is used to cut the bent wire.

[0032] Specifically, in this embodiment, the wire is fed by the infeed assembly 200. During the feeding process, the wire passes through the cutting assembly 400. After the starting end of the wire passes through the cutting assembly 400, it is clamped by the clamping assembly 300. After clamping, the clamping assembly 300 rotates the starting end of the wire by 180° to bend the wire into a 'U' shape. At this time, the subsequent mechanism of the multi-signal transmission harness production line clamps both ends of the wire simultaneously. After clamping, the cutting assembly 400 cuts the wire, thereby realizing automatic wire cutting. Through automatic feeding and cutting of the wire, the wire cutting efficiency can be improved. At the same time, the large-angle bending of the wire by the clamping assembly 300 makes it convenient for the subsequent mechanism of the production line to clamp both ends of the wire simultaneously and weld terminals to both ends of the wire at the same time. This improves the production efficiency of multi-signal transmission harnesses and effectively reduces manual labor intensity and labor costs, enabling large-scale production.

[0033] Please see Figures 3 to 5 To achieve automatic wire feeding, the wire feeding assembly 200 in this embodiment includes a drive unit 210, a wire feeding unit 220, and a guide block 230. Two sets of drive units 210 and wire feeding units 220 are respectively provided. The drive units 210 are mounted on the base 100, and the wire feeding units 220 are mounted on the drive units 210. The two sets of drive units 210 drive the two sets of wire feeding units 220 to move towards or away from each other. The guide block 230 is located between the two sets of wire feeding units 220. Guide blocks 230 are provided at both ends of the wire feeding unit 220. During wire feeding... The guide block 230 can guide the wire, and the guide block 230 has a wire hole 231. The wire can be passed through the wire hole 231 for conveying. Before conveying, the two sets of drive units 210 can drive the two sets of wire feeding units 220 to adjust the distance between the two sets of wire feeding units 220 so that the distance between the two sets of wire feeding units 220 matches the diameter of the wire. Then, the two sets of wire feeding units 220 jointly drive and guide the wire to convey it, realizing automatic conveying of the wire and enabling the conveying of wires of different diameters, thereby improving the applicability of the wire cutting mechanism.

[0034] Of course, in order to drive the two sets of wire feeding units 220 to move, the drive unit 210 includes a drive component 211 and a moving plate 212. The drive component 211 is fixedly mounted on the base 100, and the moving plate 212 is connected to the drive component 211. The wire feeding unit 220 is mounted on the moving plate 212. The drive component 211 can drive the moving plate 212 to move. When the moving plate 212 moves, it will carry the wire feeding unit 220 with it, thereby adjusting the distance between the two sets of wire feeding units 220, which is convenient for feeding wires of different diameters.

[0035] In order to deliver the wires, the wire delivery unit 220 in this embodiment includes a wire delivery motor 221, a main wire delivery wheel 222, and an auxiliary wire delivery wheel 223. The wire delivery motor 221 is installed on the lower part of the moving plate 212, while the main wire delivery wheel 222 and the auxiliary wire delivery wheel 223 are respectively located on the upper part of the moving plate 212. A transmission belt 224 is installed between the lower part of the main wire delivery wheel 222 and the output end of the wire delivery motor 221, and a wire delivery belt 225 is installed between the upper part of the main wire delivery wheel 222 and the auxiliary wire delivery wheel 223. At the same time, a plurality of limiting wheels 226 are provided between the main wire delivery wheel 222 and the auxiliary wire delivery wheel 223, and the limiting wheels 226 are in contact with the inner side of the wire delivery belt 225. During the wire feeding process, the main wire feeding wheel 222 is driven to rotate by the wire feeding motor 221 and the transmission belt 224. When the main wire feeding wheel 222 rotates, it will cause the auxiliary wire feeding wheel 223 to rotate through the wire feeding belt 225. When the wire feeding belts 225 of the two sets of wire feeding units 220 are rotating, they will squeeze and feed the wire, thereby conveying the wire forward to realize the automated wire feeding. When the wire feeding belt 225 is running, the squeezing surface of the wire feeding belt 225 can be limited by the limit wheel 226 to ensure that the wire feeding belts 225 of the two sets of wire feeding units 220 can squeeze the wire reasonably, thereby making the wire feeding smoother.

[0036] In addition, to ensure the accuracy of wire cutting, the wire feeding assembly 200 also includes an encoder wheel 240, which is located behind the wire feeding unit 220 along the wire feeding direction. An encoder 241 is installed at the lower part of the encoder wheel 240. There are two sets of encoder wheels 240. One set is set on a movable plate 212 on one side and is connected to the wire feeding motor 221 on the movable plate 212, serving as the main encoder wheel. The other set of encoder wheels 240 is set on the movable plate 212 on the other side, serving as the auxiliary encoder wheel. An encoder 241 is installed at the lower part of this encoder wheel 240. Through the cooperation of the encoder wheel 240 and the encoder 241, the wire feeding length can be precisely controlled, thereby ensuring good consistency of the wire during cutting and improving the production quality of multi-signal transmission harnesses.

[0037] Please seeFigure 6 When the wire feeding assembly 200 feeds the wire, the wire passes through the cutting assembly 400. After passing through, the starting end of the wire is clamped and rotated by the wire clamping assembly 300. Therefore, the wire clamping assembly 300 in this embodiment includes a fixed bracket 310, a rotary motor 320, a rotating block 330, and a wire clamping cylinder 340. The fixed bracket 310 is set on the base 100. The rotary motor 320 is installed on the top of the bracket 310, and the output end of the rotary motor 320 is connected to one end of the rotating block 330. The wire clamping cylinder 340 is connected to the other end of the rotating block 330. The rotary motor 320 can drive the rotating block 330 to rotate 180° so that the wire clamping cylinder 340 can rotate. A gripper 350 is connected to the output end of the wire clamping cylinder 340.

[0038] After the starting end of the wire passes through the cutting assembly 400, the clamping cylinder 340 drives the gripper 350 to clamp the starting end of the wire. After clamping, the rotary motor 320 drives the rotating block 330 to rotate 180°. When the rotating block 330 rotates, it will also rotate the clamping cylinder 340 installed at one end, thereby causing the gripper 350 to bend the starting end of the wire at a large angle, making the wire into a 'U' shape. At this time, the subsequent mechanism of the multi-signal transmission harness production line clamps both ends of the wire simultaneously. After clamping, the cutting assembly 400 cuts the wire. After cutting, terminals can be welded to both ends of the wire at the same time, thereby improving the production efficiency of multi-signal transmission harnesses and effectively reducing manual labor intensity and labor costs, realizing large-scale production.

[0039] Please see Figure 7 In this embodiment, to facilitate wire cutting, the cutting assembly 400 includes a mounting frame 410, a cutting cylinder 420, and a cutter 430. The mounting frame 410 is mounted on the base 100, and cutting cylinders 420 are fixed on both sides of the mounting frame 410. The two sets of cutting cylinders 420 are arranged opposite to each other. A cutter fixing block 440 is connected to the output end of each set of cutting cylinders 420, and a cutter 430 is provided on each set of cutter fixing blocks 440. The cutting cylinder 420 can drive the cutter fixing blocks 440 to move, thereby causing the cutters 430 on the two sets of cutter fixing blocks 440 to move towards or away from each other. After the wire clamping assembly 300 bends the wire at a large angle, the subsequent mechanism on the production line will clamp both ends of the wire simultaneously. At this time, the cutting cylinder 420 will drive the cutting blade fixing block 440 to move, thereby causing the cutting blades 430 on the two sets of cutting blade fixing blocks 440 to move towards each other. The two sets of cutting blades 430 will then cut the wire by staggering, thereby realizing automatic cutting of the wire, improving the wire cutting efficiency, and reducing manual labor intensity and labor costs.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
